Abstract :
It is proposed that the autoregressive coefficients (as computed from the estimated autocorrelation function) in an autoregressive spectral estimation scheme may be used for feature extraction purposes. An example is presented where such extractors are used to describe seismic wave traces originating from shallow earthquakes and underground nuclear explosions.
